Bright light Emitted from Smartphones Affects the Body's Biological Clock

It has been proven that at night, bright light (emitted from smartphones, laptops, etc.) affects the body's biological clock and increases the risk of insomnia.

This physical clock plays an important role in health and increases the risk of other diseases, including cancer, cardiovascular disease, obesity and diabetes type two, affecting the night cycle.

And now scientists have fixed the cells in the eyes that work to reset the physical clock system by determining the ambient light.

These cells were determined in the research of the American Seeker Institute for Biological Studies and it was reported that when these cells are exposed to artificial light at night, our internal clock becomes confused, resulting in various medical problems. Can get out

Doing different things using a mobile phone increases the pressure that increases the stress hormone cortisol excretion in the brain, which increases the activity of the brain and does not calm the skin.

This is why in the past it has been suggested that one or two hours before going to sleep the screen should be discontinued.

Researchers have found that these cells are most sensitive to blue light and are used in general LED lights and other devices such as smartphones and laptops.

Other experiments have shown that one type of cells react to this light immediately, but it takes a long time to take effect, the other takes time to activate, but it also takes longer to dissipate. Whereas the third type responds when the light is too high and the effect disappears as soon as it is turned off.

This new research also explains why some blind people cannot see but their biological clock. Being aware of the night cycle and how they perceive the light.

According to the researchers, it is clear that these cells, called IPRGCS, send light signals to the brain, and blind people can determine the day or night with their help.

He said the results prove that TVs, computer monitors, and smartphone screens should be designed in a way that does not allow blue light to affect the brain.

According to him, we will now investigate the effects of light, intensity, and duration of different colors on these cells.

Researchers said that experiments on donations made by individuals of different ages will help us understand how these cells function differently in young and elderly people.
